Give me a day and I'll implement it in my agent-oriented IRC server https://github.com/marlinski/airc !

Cool. I did something like that so agents and people could communicate with a Jira instance using Websocket-aware IRC and a browser-based client based on superchat.

Put the issue context in a #channel and invite external parties/entities, bring the results back to the work.

I have tested it but the complexity didn't justify the results in my experiment. I couldn't get it accepted into Atlassian Marketplace, either.
